public class OpProcedure extends Op1
General procedure in algebra evaluation (a stored procedure facility) Syntax (ARQ extension): CALL <iri>(?x, ?y+3). See also the similar algebra form for property functions. The difference is in argument handling. A property function has a URI and two argument lists, one for subject, one for objects. A procedure is a URI and a list of arguments.
